摘要： An apparatus is provided to handle classes of data in computer systems that must not be permitted to intermingle due to their security classifications or criticality of their data content, as in banking or safety applications. An isolated path is established for transmitting a given class of data between elements of the computer system with assurance that the data has been transmitted from the proper source, has been received by an authorized recipient and that unauthorized elements of the system have not intercepted or altered the data. Plug in type secure bus arbiter (SBA) module or bus arbiter interconnect module (10) with a controller (11) provide a way to isolate data without modification of the computer back plane or motherboard in a computer chassis (12). Modules can be used with commercial off the shelf (COTS) and non-development item (NDI) cards for a wide variety of standard computer printed circuit boards.
摘要翻译：提供了一种装置，用于处理计算机系统中的数据类别，由于其安全分类或其数据内容的关键性，不能被允许混合，如银行或安全应用程序。建立隔离路径，用于在计算机系统的元件之间传送给定类别的数据，确保数据已经从适当的来源发送，已被授权的接收者接收，并且系统的未授权元件未被拦截或改变数据。带有控制器（11）的插入式安全总线仲裁器（SBA）模块或总线仲裁器互连模块（10）提供隔离数据的方法，而不改变计算机机箱（12）中的计算机背板或主板。模块可与商业现货（COTS）和非开发项目（NDI）卡一起用于各种标准计算机印刷电路板。

摘要： An information transfer system (ITS) (10) is capable of providing interoperability among a large number of external communications systems that each use different signal formats. The ITS (10) includes a group of interface units having a plurality of wireless interface units (12a-12n) for converting between a plurality of wireless signal formats and a common signal format and a plurality of wired interface units (14a-14n) for converting between a plurality of wired signal formats and the common signal format. In addition, the ITS (10) includes a switch (16) for selectively establishing connections between interface units in the group of interface units. Some or all of the interface units are dynamically reconfigurable for supporting new or changing signal formats.
摘要翻译：信息传输系统（ITS）（10）能够提供各种使用不同信号格式的大量外部通信系统之间的互操作性。 ITS（10）包括一组具有多个无线接口单元（12a-12n）的接口单元，用于在多个无线信号格式和公共信号格式之间转换和多个有线接口单元（14a-14n），用于在多个有线信号格式和公共信号格式之间进行转换。另外，ITS（10）包括用于选择性地建立接口单元组中的接口单元之间的连接的开关（16）。部分或全部接口单元是动态可重构的，用于支持新的或改变的信号格式。
